The data newsletter by @puntofisso.
Hello, regular readers, and welcome, new ones! :)
This is Quantum of Sollazzo, the newsletter about all things data. I am Giuseppe Sollazzo, or @puntofisso. I’ve been sending this newsletter since 2012 to be a summary of all the articles with or about data that captured my attention over the previous week.
The newsletter is and will always (well, for as long as I can keep going!) be free, but you’re welcome to become a friend via the links below.
The most clicked link in issue 497 last week was to Alasdair Rae’s brilliant maps of working from home in England and Wales, 2011 vs 2021.
I hope your festive break is going great. See you in the new year.
‘till next week,

USAFacts’ “snapshot of 2022 in federal spending, elections, crime rates and more.“
Although this guide is mostly aimed at Machine Learning pipelines, I think it will also be useful if you’re trying to do any type of data analysis that requires heavy data cleaning and calculations that go beyond the mere average/median/etc. Repository is here, with the TOC here.
“This repository shares example code and example prompts for accomplishing common tasks with the OpenAI API.“
“This is a static website that you can run. It is a website that takes in your Twitter archive zip file, in the format that it is provided circa December 2022, and generates a zip file with another website in it.“
“There are other ways of crushing a multicolored image down to 1-bit monochrome but I think Atkinson’s method produces quite striking results that I thought would look neat on the modern web.“
I find dithering rather intriguing, for some reason. Dithered images have some interesting properties, including the fact that resizing ruins them way more than for non-dithered pictures.
The peculiarity of the approach in this article is that it is done in the UI thread (all code is here).

“With this year’s holiday approaching, I was wondering if I had ever witnessed a real white Christmas”, says Simon Jockers from Datawrapper.
